Is there life at the bottom of the Mariana Trench?
The Mariana Trench is deeper than Mount Everest is tall and anything living there has to survive the cold water and extremely high pressure. Some animals, including the deep-sea crustaceans Hirondellea gigas , do live there —and they have recently had a human visitor.
How deep is the deepest part of the ocean?
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
What is the deepest trench in the world?
The Mariana Trench—the deepest point in the ocean—extends nearly 10,975 meters (36,000 feet) down in a remote part of the Pacific Ocean. But if you thought the trench could escape the global onslaught of plastics pollution, you would be wrong.
What caused the Mariana Trench to be so deep?
The Mariana Trench was formed through a process called subduction. Earth's crust is made up of comparably thin plates that “float” on the molten rock of the planet's mantle. While floating on the mantle, the edges of these plates slowly bump into each other and sometimes even collide head-on.
